摘要： 研究开发一种能够接收和保存多媒体广告信息的VoIP设备，提出其广告服务模型。该VoIP设备能够将接收到的广告信息保存在其内部的存储器上，并且可以随时将对用户有用的广告信息迅速地传递给用户。实验表明，该设备每条核心指令的执行时间约为18 ms，每秒钟可以处理10~12次通话过程，接收器软件处理的时间仅需要4 ms，接通和断开一个外部电话仅需要93 ms的时间，比现有的网络电话通信方法在通话完成率方面具有更明显的优势。

Abstract: A VoIP device is intended to be developed, which can receive and save multimedia advertisement information, and its advertisement service model is presented. The VoIP device can save the advertisement information received from a push server of common carriers in its internal storage, and only the information which is necessary for a user is delivered promptly at any time. The experiment shows that its processing time per kernel instruction is only 18 ms, and it can process 10 ~ 12 calls per second. The time for software processing is only 4 ms and the average time for finishing once connecting and disconnecting an outbound call takes only 93 ms. It is more advantageous in call completion rate than current VoIP communication devices.
